Cadence's ML-based Cerebrus automates and scales digital chip design, enabling customers to efficiently achieve demanding chip design goals.

Cadence Design Systems Inc. has launched Cerebrus Intelligent Chip Explorer, a new machine learning (ML)-based tool that automates and scales digital chip design, enabling customers to efficiently achieve demanding chip design goals. The combination of Cerebrus and the Cadence RTL-to-signoff flow offers advanced chip designers, CAD teams and IP developers the ability to improve engineering productivity by up to 10X versus a manual approach while also realizing up to a 20% better power, performance and area (PPA).

With the addition of Cerebrus to the broader digital product portfolio, Cadence offers the industry’s most advanced ML-enabled digital full flow, from synthesis through implementation and signoff.​ The new tool is cloud enabled and utilizes highly scalable compute resources from leading cloud providers to rapidly meet design requirements across a wide range of markets including consumer, hyperscale computing, 5G communications, automotive and mobile.

Cerebrus features Reinforcement ML, which quickly finds flow solutions human engineers might not naturally try or explore, thereby improving PPA and productivity; and ML model reuse, which allows design learnings to be automatically applied to future designs, reducing the time to better results. With Cerebrus, a single engineer can optimize the complete RTL-to-GDS flow automatically for many blocks concurrently, allowing full design teams to be more productive. It provides scalable on-premises or cloud-based design exploration for faster flow optimization, as well as feature a powerful user cockpit that allows interactive results analytics and run management to gain valuable insights into design metrics.

“Previously, design teams didn’t have an automated way to reuse historical design knowledge, leading to excess time spent on manual re-learning with each new project and lost margins,” said Dr. Chin-Chi Teng, senior vice president and general manager in the Digital & Signoff Group at Cadence. “The delivery of Cerebrus marks an EDA industry revolution with ML-driven digital chip design where engineering teams have a greater opportunity to provide higher impact in their organizations because they can offload manual processes. As the industry continues to move to advanced nodes and design size and complexity increase, Cerebrus lets designers achieve PPA goals much more efficiently.”

Cerebrus is part of the broader Cadence digital full flow, working seamlessly with the Genus Synthesis Solution, Innovus Implementation System, Tempus Timing Signoff Solution, Joules RTL Power Solution, Voltus IC Power Integrity Solution and Pegasus Verification System to provide customers with a fast path to design closure and better predictability. The new tool and the broader flow support the company’s Intelligent System Design strategy, which enables pervasive intelligence for design excellence.

“To efficiently maximize the performance of new products that use emerging process nodes, digital implementation flows used by our engineering team need to be continuously updated. Automated design flow optimization is critical for realizing product development at a much higher throughput,” said Satoshi Shibatani, director, Digital Design Technology Department, Shared R&D EDA Division, at Renesas. “Cerebrus, with its innovative ML capabilities, and the Cadence RTL-to-signoff tools have provided automated flow optimization and floorplan exploration, improving design performance by more than 10%. Following this success, the new approach will be adopted in the development of our latest design projects.”

“As Samsung Foundry continues to deploy up-to-date process nodes, the efficiency of our Design Technology Co-Optimization (DTCO) program is very important, and we are always looking for innovative ways to exceed PPA in chip implementation. As part of our long-term partnership with Cadence, Samsung Foundry has used Cerebrus and the Cadence digital implementation flow on multiple applications. We’ve observed more than an 8% power reduction on some of our most critical blocks in just a few days versus many months of manual effort. In addition, we are using Cerebrus for automated floorplan power distribution network sizing, which has resulted in more than 50% better final design timing. Due to Cerebrus and the digital implementation flow delivering better PPA and significant productivity improvements, the solution has become a valuable addition to our DTCO program,” said Sangyun Kim, vice president, Design Technology, Samsung Foundry.
